2 Claims.

This invention relates to refrigerating apparatus for cooling both bottled and tap beverages.

The invention will be found to reside in a compact cabinet having a compartment therein for receiving a barrel or other container, a compartment for housing a refrigeratingdevice, and a third compartment insulated from the remaining compartments and containing an evaporator and a cooling coil communicating with the liquid container.

' Various novel structural features of the cabinet are more fully described in the following specifications and drawings, wherein:

Fig. 1 is a perspective view of the cabinet with l5 both covers removed.

Fig. 2 is a plan of the cabinet with the top cover removed.

Fig. 3 is a section on line 3--3 of Fig. 2 with the refrigerating unit shown in broken lines.

Fig. 4 is an enlarged section on the line 4 4 of Fig. 2 with portions broken away to show the wall structure.

Fig. 5 is an enlarged section on the line 5-5 of Fig. 4.

Fig. 6 is an enlarged section on the line 6 6 of Fig. 2.

Fig. 7 is an enlarged section on the line 7--7 of Fig. 3.

Fig. 8 is a plan of one corner of the cooling compartment with the finishing channels removed.

In the drawings the numeral 10 indicates a cabinet generally rectilinear in shape and having an open top entering a container compartment 11 extending to the bottom of the cabinet, and a relatively shallow cooling compartment 12 providing therebeneath a compartment 13 for housing the motive elements 14 of a refrigerator unit.

The cooling compartment 12 contains a serpentine expansion coil 16, preferably of the type disclosed in copending application Serial No. 601,749, led March 29, 1932, now Patent No. 1,913,345, patented June 6, 1933, wherein the convolutions are formed to provide a plurality of bottle receiving aisles 17. The coil is connected to a refrigerant supply mechanism of any suitable type, herein shown as a dry system having a motor-compressor unit 18 mounted in the compartment 13, by means of which refrigerant is delivered to a condenser 19, and thence to the coil 16 through an input pipe 21, where evaporation and expansion of the refrigerant occurs for subsequent return to the compressor through the output pipe 22.

A liquid cooling coil 23 is also mounted in the i5 compartment 12 and its convolutions 24 closely follow the convolutions of the expansion coil 16. One end 20 of this coil extends into the container compartment 11 for connection to a liquid container, such as a barrel, 25, while the remaining extremity 30 terminates externally of the cabinet 60 in a draft arm having a tap valve 26. The liquid in the container 25 and in the coil 23 is mamtained under pressure so that when the tap 26 is opened the liquid'may discharge therefrom. For exemplary purposes, the pressure means is shown as a hand pump 27, secured to the cabinet and connected to deliver 'air or-gas under pressure to the container 25. Theoperating handle of this pump extends through the side wall of the compartment 12 where it may be readily manipulated. 70

Referring more particularly to the cabinet structure, it will be observed that the supporting frame thereof consists of vertical angle iron corner posts 31 and upper and lower angle iron tie members 32 and 33. These members are bent into 75 a continuous rectangular shape and the corners thereof are notched, as indicated by the numeral 34 (Fig. 8), to provide receiving sockets for the posts 31, which are welded thereto to form a rigid structure.

A sub-frame 36 is mounted within the described structure intermediate the upper and lower tie vmembers 32 and 33, and it comprises an angle member bent to extend across the sides and one end thereof and notched at its corners and free y extremities'to engage the posts 31 to which it is welded. A transverse supporting angle 37 is secured to the longitudinal legs of the sub-frame 36 to provide therewith a mounting for the hereinafter described cooling compartment 12. A second transverse member 3810i cruciform structure cross-connectsv the longitudinal legs of the lower tie member 33 to the longitudinal legs of the subframe, thus reinforcing the structure against diagonal strains.

, The structure described is covered with sheet metal to form side panels 39 and 41 and end panels 42 and 43, allexcept the latter panel being rigidly secured to the vertical angle iron legs of the posts, frames and sub-frame. The upper tie member 3l and the panels are enclosed at their top edge by a finishing member 45 which is channel shaped in cross section and provided with depending legs 46 engaging the inner edge of this tie member and the outer surface of the panels respectively.

The panel 43 is removable (Figs. 3 and 6), to permit easy access to the container compartment 13 and and it is reinforced to prevent exure during removal by horizontal and vertical straps 47 and 48, the latter straps terminating at their lower extremities in hook portions 49 adapted to engage in the space 51 between the finishing member 45 and the tie member 32 and moved upwardly to permit engagement of the hook portions 49 with of the cabinet can b the lower tie member 33, whereupon the panel is dropped to permit the seating of the hook portions vas shown in full lines in Fig. 3.

The bottom of the container compartment 11 is formed of a plurality of spaced cross members 53 which are secured to opposite legs of the lower tie member 33. The remainder of the cabinet bottom is left. open to provide for air entry to supply the fan 54 of the motor-compressor unit 18. The air, after being forced through the condenser 19, exhausts through a port 54'formed n the end panel 42.

The cooling compartment 12 is formed of a core 55 of an insulating material, such as sheet fiber or cork, having a sheet` metal liner 56 and an exterior casing formed by the adjacent sides and end panels of the cabinet and end and bottom plates 57. and 58 coveringvthe remaining faces thereof. The bottom of this compartment member is supported r,on the sub-frame 36 and the cross member 37. Y

The core 55 is slotted vertically at 61 and 62 and its bottom plate 58 and liner 56 are pierced to provide an entry through which extend the input and output pipes 21 and 22 of the evaporator coil. 16 for connection to the condenser and compressor. The ends 20 and 30 of the cooling coil 23 extend through holes 59 of the transverse wall of the cooling compartment and enter the container compartment 11 for the previously described connection with the liquid container.

Both the cooling compartment 12 and the container compartment 1l are covered byl a cover member 67 which comprises two hinged sections 68 and 69 each overlying one of the compartments. The sections are eac provided with a flange portion 71 adapted to rest on the finishing member 45 of the outer wall of the cabinet, and

Witha central portion 65ada'pted to be received within the comparments. f

The cabinet is mounted; on casters 73 which are secured to the lower corners thereof, whereby the device may be easily conveyed either to an rinconspicuous location when not in use, or to a supply room for changing/ containers.

Referring to Fig. 1, it will be noted that the panel 43 iseasily re/niovable to expose an exhausted container or barrel and that the top 67 folded back to expose the portions of the pump unit entering the container, upon removal of which, the barrel is readily removed through the open side of the cabinet and replaced by a full barrel, whereupon the pump is connected,` the panel 43 and the cover replaced, and the pump operated to bring the pressures in the barrel and coil to the desired degree. During From the foregoing description, it will be understood that the invention provides a self-contained refrigerating unit in cabinet form, in which provision is made for quickly cooling both bottled or packaged goods and bulk liquids, and in which ready access may be had to both packaged and bulk liquid compartments. It will also be appreciated that the invention provides a novel form of refrigerating cabinet, and that the various features of the invention specifically described herein are but illustrative of the scope thereof, as set forth in the following claims.
